Corona Loss Measurements for the Design of Transmission Lines to Operate at Voltages Between 220 Kv. and 330 Kv.

Corona loss measurements were obtained on conductors of three different diameters; namely, 1.125 in., 1.49 in. and 2.0 in. Voltages up to 600-kv. line voltage were used in these measurements. Various surface conditions of the 1.125-in. cable were studied. These measurements include tests on the new cable as received, the cable as washed, scratch brushed, buffed and dragged. The aging of the dragged cable was observed for seven months. Data were obtained on the daily variation of loss. The effects of configuration and transposition were studied on No. 22 wire. A description of the modifications in the high-voltage wattmeter for these high-voltage measurements is reported.
